Description Methods References See Also Examples

Description

These methods are straight-forward implementations of the corresponding generic functions. However, for complex data like array are just transferred as a string instead of the corresponding vector in R. This behavior will change in future releases, and the author is advised not to rely on it.

Methods

conn

an PostgreSQLConnection object.

statement

a character vector of length 1 with the SQL statement.

res

an PostgreSQLResult object.

...

additional parameters.
